Patch 0 for
SLE 15 SP3)
An update that fixes 10 vulnerabilities is now available.
Description:
This update for the Linux Kernel 5.3.18-57 fixes several issues.
The following security issues were fixed:
o CVE-2022-0185: Incorrect param length parsing in legacy_parse_param which
could have led to a local privilege escalation (bsc#1194517).
o CVE-2021-4154: Fixed option parsing with cgroups version 1 (bsc#1193842).
o CVE-2021-4028: Fixed use-after-free in RDMA listen() that could lead to DoS
or privilege escalation by a local attacker (bsc#1193167).
o CVE-2020-3702: Fixed a bug which could be triggered with specifically timed
and handcrafted traffic and cause internal errors in a WLAN device that
lead to improper layer 2 Wi-Fi encryption with a consequent possibility of
information disclosure. (bsc#1191193)
o CVE-2020-25670, CVE-2020-25671, CVE-2020-25672, CVE-2020-25673,
CVE-2021-23134: Fixed multiple bugs in NFC subsytem (bsc#1178181, bsc#
1186060).
o CVE-2021-42739: The firewire subsystem had a buffer overflow related to
drivers/media/firewire/firedtv-avc.c and drivers/media/firewire/
firedtv-ci.c, because avc_ca_pmt mishandled bounds checking (bsc#1184673).
